Description

The utility model relates to equipment for processing rubber products and can be used to extract side rings from tires to be disposed of.

A device for extracting rings from worn tires, patent for utility model No. 29004, publ. 04/27/2003, B29B 17/02. The known device comprises a reciprocating drive, a hook for gripping the side ring and an inclined stop with an opening for the passage of the hook and the removable side ring. Distinctive features of the known device are: making an inclined stop in the form of detachable plates with cutting edges forming an opening for the passage of the hook and the side ring to be removed, setting the inclined stop in such a way that the angle between the direction of the hook travel and the tire moving direction in the process of removing the side ring is less 90 °, while the thickness of the hook for gripping the bead ring is greater than the minimum cross-sectional dimension of the bead ring.

The hydraulic cord drawer of the DS series, manufactured by the Technoresource company (Nakhodka), is known (see the information on the website: http://www.stanki-ru.ru/stanki-dlya-pererabotki-shin/vytyagivatel-provoloki .html) selected as the closest equivalent. The known cord extender includes a hook for gripping the side ring, an emphasis in the form of a plate with a slot for holding a worn tire, a pressure hydraulic cylinder with a nozzle for pressing the side ring to the hook, a main hydraulic cylinder moving the hook, horizontal guides of the main hydraulic cylinder that prevent it from shifting or turning during work.

Known devices can eliminate the rupture of the side rings during removal and ensuring their complete removal from the treated part of the tire. In known devices, the movement of the main working body is carried out in a horizontal plane. A disadvantage of the known devices is that they require quite large production areas for their placement due to the large size. In addition, these devices have a large metal consumption, due to their large dimensions.

The technical result is to reduce the size of the device for extracting rings from worn tires and, as a result, reducing the metal consumption of the device.

The technical result is achieved due to the fact that a device for extracting side rings from worn tires, comprising a hook for gripping the side ring, a plate with a slot for holding a worn tire, a pressure hydraulic cylinder with a nozzle, comprising a hook moving mechanism including a beam on which the hook is fixed and a clamping hydraulic cylinder, vertical cylindrical guides along which the beam moves, hydraulic cylinders raising the beam along the guides, the mechanism for lowering the beam. Mostly the beam moves along the guides by means of a sliding sleeve. Advantageously, the proposed device comprises two telescopic cylinders raising the beam along the guides.

The utility model is illustrated by the following graphic material:

In FIG. 1 shows a General view of a device for removing side rings from worn tires.

A device for extracting side rings from worn tires contains a frame 1, a beam 2, a hook for gripping a side ring 3, a clamping hydraulic cylinder 4, vertical cylindrical guides 5, telescopic hydraulic cylinders 6, a plate with a slot for holding a worn tire 7, a hydraulic station (in Fig. Not shown), the lowering mechanism of the beam 8, the control panel (not shown in Fig.). The hook 3 is fixed on the beam 2, which is pushed upward by two telescopic hydraulic cylinders 6. The guides 5 do not allow the beam 2 to shift or rotate during operation. The clamping hydraulic cylinder 4 presses the side ring to the hook 3 and prevents it from breaking or slipping. The lowering mechanism of the beam 8 provides the beam downward movement and, in particular, may consist of a drive shaft with two sprockets and hydraulic drive, two sprockets with tensioning mechanisms and two chains. However, this embodiment of the lowering mechanism of the beam does not limit other versions of this mechanism, which may be different.

The proposed device operates as follows.

The tire to be processed is fixed to the hook 3. The telescopic hydraulic cylinders 6 are actuated, and the beam 2 with the hook 3 starts to move up. Hook 3 presses the tire against the slit plate 7 and, passing through the slot, breaks the tire and begins to release the bead ring. After the hook 3 has passed through the plate 7, its movement stops. Then, the clamping hydraulic cylinder is driven, as a result of which, with a special nozzle, it presses the bead ring to hook 3, preventing it from slipping or breaking. Without releasing the pressure of the bead ring, hook 3 continues to rise until the bead ring is completely released. After that, the clamping hydraulic cylinder returns to its original position, the operator removes the bead ring from the hook. The beam 2 with the hook 3 is lowered under its own weight using the lowering mechanism of the beam 8. After which the cycle of work is repeated.

It is obvious that the proposed device for extracting rings from worn tires can reduce the dimensions of the device, and as a result, reduce its metal consumption.
